Change the Mac System Font to the OS X El Capitan Font in OS X Yosemite

When the San Francisco type face first debuted it was made for the Apple Watch, but some enterprising Mac users modified the San Francisco font to run in OS X Yosemite anyway. Fast forward to now, and the San Francisco font has been revised by Apple to be a bit more readable for the Mac desktop and iOS devices, as it will soon replace Helvetica Neue as the default system font in iOS 9 and OS X El Capitan. That font has been released for specific use by Apple (available here), but if you’re currently running OS X Yosemite, you can use a copy of the modified version of the El Capitan system font right now.
To be perfectly clear, the OS X El Capitan San Francisco system font is different from the Apple Watch variant of San Francisco, which has since been renamed to San Francisco Compact, intended for watchOS. In other words, if you installed the Apple Watch font onto your Mac, it’s not quite the same as the one mentioned here.
